More dense atmosphere means strapping some feathers to your arms and flapping like a bird could actually work.
This would work best in an atmosphere of tungsten hexafluoride, which is the heaviest gas in the world. It's ~11 times heavier than air. The downside is that you would melt down to a brown sludge.
It's the sludge part that really throws a wrench into it for me.
What if I'm already brown sludge?
Sounds like a win to me
Wait how does Hydrogen -> Ozone?
It doesn't... I may have replaced the wrong text.
In any case, what would you say is the best property of having more hydrogen gas in the atmosphere? Make it quick, I need to sell a few pentawatthours to world leaders.
It floats up and gets striped first by solar winds, like a shield protecting the ozone layer.
We can react the hydrogen with CO2 in the atmosphere to produce hydrocarbons and water. The water goes back into the electrolysis system, and the hydrocarbons can be put back underground where they belong. As a bonus it gets rid of some extra CO2!
Hydrogen is its normal state exceeds the escape velocity of Earth
Capture it and use it for nuclear fusion.
Then capture the helium produced as a byproduct and use it to build a city supported entirely by weather balloons
Human fusion technology currently only works with heavy hydrogen isotopes (deuterium and tritium in neutronic fusion). Fusion of normal hydrogen requires pressures and temperatures we're unable to control at the moment.
Aneutronic fusion is currently explored in fusing hydrogen and bor, this results in clean helium-4 and no neutron radiation, meaning it leaves no radioactive waste. But it needs temperatures FAR exceeding the core of the sun and it's self-cooling via Bremsstrahlung, so it's nowhere near a working technology.
Okay mr guy with your science and facts!
How does the saying go, the only thing that can stop a bad air pollutant with a gun is a good air pollutant with a gun?
Why is the 2 in CO2 superscript? Numbers like that are always subscript.
The solution to global warming is to artificially heat earth to Planck temperature, this ensuring it cannot possibly become any hotter.
Not to mention we fix that pesky sea level rising bit.
This diagram is wrong on so many levels. Ozone is "charged Oxygen" (O1 rather than the usual O2) so it's saying you get Ozone out of the Hydrogen side. The bubbles are forming in a place where they can't get to the output vents, so the accumulating gases would slowly force the water level in the inner chamber down, and thus up through the vents. It's pretty shit. Is it AI slop?
ozone is 0₃
Putting Ozone on the Hydrogen side was my mistake, I haphazardly added the hearts last minute and just put 2 great things about the gases there, not realising they were about the same gas. For what it's worth, you got it wrong too, as Ozone is O~3~.
The diagram itself is from here. While there are plenty of reasons to doubt the promises of clean hydrogen companies, I at the very least trusted them when it comes to understanding electrolysis... might want to rethink that. But AI it is not, as far as I can tell.
You're quite right, Ozone is actually O~3~, I got that wrong. I should have looked it up, but I didn't, hence the error. I'm so sorry I mislead you - can you forgive me? Ozone is actually very interesting - did you know there is a layer of the upper atmosphere known as The Ozone Layer, and that it has a hole in it? Also, Ozone is sometimes produced by chemical reactions and electrical arcs - it has a distinctive, Ozoney smell. As you also made mistakes, I think we are now even - have you ever considered taking up a career as a Large Language Model?
Even if this would work without any complications from increasing atmospheric pressure, electrolyzing 0.5% of the ocean with present-day technology would take more than 200,000 years. That's plenty of time to invent new tech to speed it up, but even if some miracle invention next week sped it up by 2 orders of magnitude, it would still take more than 2000 years. So in feasibility terms I would rate this concept lower than building space elevators to save rocket fuel.
Cool sci-fi concept tho - let's get Arnold on it right away!
I don't think adding other gases will reduce the amount of radiation carbon dioxide absorbs lol
But the scary news are always "Carbon dioxide reached 430 parts per million". So I thought instead of reducing the carbon, we could increase the "per million" for the same effect and have no scary news any more!
It will dilute it and reduce the effect, sorta like reducing the reflectivity of a mirror.
I don't think so. There's still the same amount of carbon between the earth and space, so it's still going to have the same effect of blocking IR that's moving to escape the earth's climate system.
If anything the extra gases will simply trap more heat on their own, although probably less so than the CO2 does.
The concentration matters, not the absolute amount. Spectroscopy confirms this. 1g of CO2 will reflect IR much differently if it’s in 1mL or 1L of volume.
The volume doesn't change. It's still the same amount of CO2 in the same volume. There's just more of the other gasses in that same volume.
I don’t know enough about planets and atmospheres to say for sure, but I reckon adding gas would increase the volume of our atmosphere to some extent.
Since it's not clear what will happen let's just try. What could go wrong?
Well I'm no expert but that does not make sense to me. I don't think CO2 is reflecting IR but rather absorbing it.
Not sure where I can read more about this to confirm or deny this idea.
It’s absorption and re-emission of IR. Instead of IR leaving our planet, some gets redirected back at the surface by CO2.
Ok, ok, ok. But hear me out. Instead of ozone, zeppelins!
What could go wrong, I wonder
"Oh, the humanity!"
HUH?!! WHATS THAT? I CANT HEAR YOU OUT OF THE BLOOD IN MY EARS.
wouldnt it be easier to have more photosynthetic organisms, like ocean algae and rainforests.
This is an ironic post
Obviously ocean algae and rainforests are superior
